The 1988 Washington Quarter is a piece of U.S. currency, part of the Washington quarter series minted since 1932.
Made of a copper-nickel clad, the quarter features George Washington on the obverse and an eagle on the reverse.
Value is influenced by mint mark location: 'P' for Philadelphia, 'D' for Denver, and 'S' for San Francisco.
Uncirculated quarters or those with errors can fetch higher prices among collectors.
Special sets, like the 1988-S Proof, can be more valuable due to their high-quality strike and finish.
Condition grades such as MS (Mint State) or PR (Proof) significantly affect a quarter's market value.
Check for rare errors like off-center strikes or double dies, which can increase a quarter's worth.
The average circulated 1988 quarter is generally worth its face value of 25 cents.
Always consult a professional coin appraiser to accurately assess your 1988 Washington Quarter's value.
